Hi all,

I've developed PunQLite. UnQLite NoSQL database binding for Pharo.

UnQLite is a fast, lightweight, portable, embedded KVS with a simple
scripting engine (Jx9).

Torsen kindly wrote about PunQLite project's beginning on his blog.

At that time, it was only a bare NativeBoost FFI interface. Now it has
become a full-fledged wrapper.

db := PqDatabase open: 'test.db'.
db at: 'Smalltalk' put: 'COOL'.
db at: 'Pharo' put: 'HOT'.
db at: 'Smalltalk' ifPresent: [:data |
    data asString inspect
Transcript cr; show: db keys.
db do: [:cursor |
    Transcript cr; show: cursor currentStringKey; space; show: cursor
db close.

Moreover, it is quite fast. I wrote a simple benchmark that does many
round-trips (put/get 100000 small elements). The result is 877 msecs
(on my windows laptop). It was impressive.
